    since i have found no really good pics for my repair on the whole internet to find the resistance of a burnt resistor...

    i took some high res pics of the AL1860 where is possible to read the markings and color codes of the resistors for reference.

    also added an infrared picure where u can see, beside may changed 5W resistor ( 5,6k ) , there a 2 other heaters (220k & 820) that might be upgraded...

    Circuit board with resistors, capacitors, coils, relay, and heat sinks, top view. Close-up of a PCB with electronic components, coils, capacitors, and heat sinks PCB with power-supply parts: relay, coils, capacitors, heatsink, and connected wiresThermal image of electronic components with temperature readouts: max 46.3°C, min 20.8°C.


    since the pictures gets recompressed see the attachments for full resolution

    Yes, but the ELEKTRODA forum system when you post a picture with the "Add picture" option makes modifications and we see a fog and probably not what you wanted to post. That is why I suggest to post such pictures in the option "add attachment" - you can have a look at the pictures added in both above mentioned options and compare yourself and you will draw your own conclusions.... If I am wrong, I apologise, but I do not see the colours clearly.... Therefore, I have a request: post the photos still as attachments and download the ones from the "image" option and the ones from the "attachment" option and compare the size of the files themselves as well as the quality, i.e. what I wrote above....

    A small note on colours - they will be natural if the tile is lit by daylight.

    i already noticed that the pictures get terribly recompressed on upload. there where originally made with an EOS6D which takes impressive pictures. my solution is to reate a git hub repo and put the pictures there, but i´ll try the attachments, too. thx.

    any other pics of this unit needed while im at it?
